|
Programming and Debugging |
|
========================= |
|
|
|
Flashing an application |
|
----------------------- |
|
|
|
Connect your device to your host computer using the JLINK USB port. |
|
The sample application :ref:`hello_world` is used for this example. |
|
Build the Zephyr kernel and application, then flash it to the device: |
|
|
|
.. zephyr-app-commands:: |
|
:zephyr-app: samples/hello_world |
|
:board: apollo4p_evb |
|
:goals: flash |
|
|
|
.. note:: |
|
``west flash`` requires `SEGGER J-Link software`_ and `pylink`_ Python module |
|
to be installed on you host computer. |
|
|
|
Open a serial terminal (minicom, putty, etc.) with the following settings: |
|
|
|
- Speed: 115200 |
|
- Data: 8 bits |
|
- Parity: None |
|
- Stop bits: 1 |
|
|
|
Reset the board and you should be able to see on the corresponding Serial Port |
|
the following message: |
|
|
|
.. code-block:: console |
|
